Application filed April 13, 1917. Serial NO. 161,890.

To all whom it may concern:

- Be it known that I, WILLIAM F. EMER- soN a citizen of the UnitedStates, residing at lduffalo, in the county of Erie and State. of New York,'have invented new and useful Improvements-in Grease-Cups, of which the following is a specification.

This invention relates to grease cups for the lubrication of bearings and consists in a simple and compact arrangement and construction particularly adapted for'thehandling of greasewhen put up inthe form of capsules or protectively inclosed charges of grease contained within a suitable container or wrapper'and of a form and'size to be received within the cup. A particularly desirable feature of my invention consists in an improved arrangement whichgreatly facilie tates the removal ofthe emptied containers withouthandling, thus eliminating danger 'of soiling the hands. 7

'A desirable embodiment of my invention isshown in' the accompanying drawing wherein the reference numerals of this'de scription' are applied to the corresponding parts in the several views. Therein Figure l is a vertical sectional view showing a desirable form of my invention. Fig. 2 is a similar view showing the parts in advanced container container position parts with the cap removedand the emptied exposed to be knocked off or otherwise removed. 7 1

The approved form of my invention here disclosed consists of a base portion 1 .pro-

vided with a threaded flange portion 2 adapted to be threaded to a suitable support 3 which may be a journal box or bearing of an'automobile or other part which it is 'de- In accordance with my mventionfthe grease is contained in a suitable collapsible 8 which maybe of paper and-the charge so contained is, as shown, of the and Fig. 3 is a view showing the.

proper size to 'bereceived within the cap 7 wherein it is'placed with its open end 9 corresponding in position to the open endof the cap. In operation the cap is then inserted and screwed onto the base portion land as.

will be readily understood as the cap is screwed down the grease will be fed into the bearing and the paper container collapses.

To facilitate the removal of thecollapsed container I have provided meanson thebase portion '1' adapted to prevent the crushed containeriadhering to the inside. of the cap when the cap is removed'which would necessitate troublesome manipulation tolflaccomplish its removal. The means providedfor this purpose as here disclosed consists in formingthe base'portion with an undercut annular groove 10-positioned whereby a portion of the container will be forced thereinf V 7 under the pressure from the cap in expelling thegrease. This effect is indicated in Fig.

20f the drawing and in Fig. '3 the cap is 7 shown removed with the collapsed container retainedw'on the base 1 and exposed inposition-whichperinits of its being conveniently removed bymerely. pushing itooif the base which requires no handling of the grease, as e is readily understood. As shown the groove 10 may desirably be downwardly o-inclined more readily to connect with the crushed container for the incline will assist inturning in" of the paper into clamping engagement with the base. I

It will beunderstood'that many modifical tions of my invention can bemade without departingv from the scopelthereofand it is therefore intended-that all'matter contained herein-shall be interpreted as illustrative and not in a limiting sense. l

Having described my invention I claim} LA grease-cup adapted for use with grease in containers, comprising a base por- 7 tion having a passage therethrough forthe grease, a cap adapted for connection with the base and movable relative to'the base to feed the grease and means on the base to engage a container to 'prevent'its removal with the cap.

1 2. Ina device forapplyingthe lubricant or bearings and the like, the ,combi a r a e t nation with a. grease containing capsule adapted to be collapsedjby pressure, said capsule having a closed upper end and an opemngin'the lower end, of a grease cup lower end of the capsule, said basehavinga hole for the outflow of the grease and hav ing its upper and inner end formed to en-.

gage with and to retain the collapsed capsule after the grease has'been expelled.

3. A grease cup adapted for use with grease in containers comprisingabase por- 7 tion having a passage therethrough for the grease, a cap threaded thereto to be movable relative to the base to compress the grease container and said base having a shoulder formed thereon and a groove ad acent the shoulder to'engage with the crushed container to retain it on the base on removal of the cap.

4. A grease cup adapted for use with grease in containers comprising a base portion, having a passage therethrough for the grease, means'for securing it in position, a cap threaded thereto to be movable relative to the base to compress the ease container and said base having a SlOIlldBI' formed thereon to be engaged by the crushed container to retain it on the base on removal'of the cap, said shoulder being formed by a groove in the base and said groove being inclined to guide the turning in of the container.

5. A grease cup comprising a base having a passage for the outflow of the grease, said base being adapted to be fixed in position adjacent the bearing to'be lubricated, a second part movable with relation to the base to force the grease out from a compressible capsule through the passage and to compress the capsule on the base, and means on the base to engage with and retain the capsule when the latterhas been compressed.

6. A grease cup for use with a compressible capsule containing grease, comprising a' fixed base adapted to be fixed in position adjacent the part to be lubricated and formed with a passage for the outflow of the grease, and a second part arranged to be movable with relation to the base to compress the capsule thereon'and to expel the grease from the capsule, said base being provided with a shoulder'and a groove adjacent the shoulder to engage with and retain the compressed capsule. 7. A grease cup comprising a base, a cap threaded to engage witha thread on the base and adapted to be screwed down thereon to expel the grease from a compressible capsule, and means on the upper end of the base for engaging with and retaining the compressed capsule.

8. The combination with a grease cup comprising a base having a small outlet passage for the lubricant and a cap threaded to fit the base, of a compressible grease capsule containing lubricant arranged within the cap and adapted to be'compressed between the cap and the base, aS the former is turned down on the latter, said capsule having a closed end and an open end arranged adjacent the base, andmeans on the upper end of the base to engage with the margin of the crushed capsule at its open end and retain the capsule whenthe'cap is withdrawn. v

9. Atwo part grease cup, adapted to receive a grease containing capsule of compressible material, comprising'a base, a cy: 'lindrical cap having an open lower end to admit the upper end of the base and internally threaded to engage with the same, and means on the upper end of the baseto engage with and retain the compressed capsule after the grease has been expelled and while the cap is being withdrawn.

capsule and retain the same when the latter has been compressed, and a cylindricalmetal cap having a closed upper end and an open lower end and internally threaded to enga e with said body thread.

n testimony whereof I have signed my name to this specification.
